Not officially, but it really is a small world. I've seen this happen so many times. When someone gets a professional reputation, good or bad, it carries forward across many companies. I've seen people who had such poor records, everyone knew the day they were interviewing and immediately warned the hiring manager. Word of these types of incidents travel fast.
Employer says the wrong thing, they lose big.
Employers know this and know it's not worth it.
One of these experiences was one of the things that made me rethink my drugging.
I am quite good at web development. I breeze through the tech interviews to the point that they generally note "Computer Stud" on my resume.
However, one time I showed up at a place, and they had a 1 hour tech test that involved creating a small website quickly with certain specifications -- data storage, manupulation, presentation, entry, validation, etc.
I did the test. The manager brought me into the office. He looked at my effort. He said, "This is the best anyone has EVER done on this test. Not only did you do everything asked, you caught the little trick question, and you also added error checking, data redundancy, and penetration security. Amazing."
I beamed happily.
He continued, "....but.. one of our network guys recognizes you. He told me about certain problems you were manifesting. We can't hire you."
Wow. Got my attention. Atlanta is big, but got small that afternoon.
